TECHNICAL FIELD

The present invention relates to a single-lip channel steel bar, and more particularly, to a novel improvement for enhancing drainage of a rack in a case where a single-lip channel steel bar is used as a transverse beam or/and a longitudinal beam and a flat-plate-like solar panel module or the like is placed on the transverse beam.

SUMMARY OF INVENTION Technical Problems

The conventional lipped channel steel bars are configured as described above, and hence have the following problems.

That is, as is apparent from the configurations illustrated in FIGS. 30 and 33, the solar panel module is inclined, and thus the transverse beams 2 are also inclined. As is apparent particularly from the configurations illustrated in FIGS. 30 and 31, the transverse beams 2 themselves have double-lip shapes, and hence the transverse beams 2 have a large load capacity and are less likely to bend. Regarding each transverse beam 2 disposed in an inclined posture, the transverse beam 2 has a double-lip shape, and hence rainwater 6 and the like coming from an outside are collected on an inner side of a lower lip 2 a in a case where the transverse beam 2 is inclined downward as illustrated in FIGS. 30 and 31. As a result, the transverse beam 2 is reduced in strength due to rust and the like, and hence has a problem in durability.

Advantageous Effects of Invention

The single-lip channel steel bar according to the present invention is configured as described above, and hence can provide the following effects.

That is, the single-lip channel steel bar includes: the channel steel bar body having a longitudinal shape and a grooved cross-sectional shape; the first side plate and the second side plate formed on both the side portions of the back plate of the channel steel bar body, respectively; the lip formed at the end portion of the first side plate and protruding toward the second side plate; and only the flat surface portion formed at the end portion of the second side plate.

The single-lip channel steel bar serves as the transverse beam or the longitudinal beam. Accordingly, all water falling onto the transverse beam flows downward from the second side plate, and thus is not collected. As a result, no rust occurs, and durability can be ensured for a long period of time.

Further, the transverse beam includes the single-lip channel steel bar according to claim 1.

Accordingly, water can be completely drained away from the second side plate.

Further, the transverse beam according to claim 1 includes the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and in order to incline the second side plate downward, the transverse beam is provided, through the intermediation of the inclined member having a wedge shape, on the longitudinal beam disposed in the horizontal posture. Accordingly, the second side plate is inclined downward, and hence water can be completely drained out of both the transverse beam and the longitudinal beam.

Further, the longitudinal beam according to claim 1 includes the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and the longitudinal beam is provided on the base member through the intermediation of the inclined member having a wedge shape. The transverse beam according to claim 1 includes the second side plate extending in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction of the back plate, and the transverse beam is provided on the longitudinal beam through the intermediation of the inclined member. Accordingly, even when the second side plate of each of the beams is inclined in the non-right-angled direction, the inclined member having a wedge shape is used, and thus it is possible to combine the transverse beam and the longitudinal beam in a right-angled manner, and to obtain a rack capable of achieving complete drainage.

DESCRIPTION OF EMBODIMENTS

The present invention has an object to provide a single-lip channel steel bar capable of enhancing drainage of each rack in a case where the single-lip channel steel bar is used as a transverse beam or a longitudinal beam and a flat-plate-like solar panel module or the like is placed on the transverse beam.

Embodiments

In the following, single-lip channel steel bars according to preferred embodiments of the present invention are described with reference to the drawings.

Note that, the same or corresponding components as those of the conventional example are denoted by the same reference symbols, and description thereof is omitted.

Reference numeral 4 of FIG. 1 denotes base members. Longitudinal beams 3 are supported in an inclined state on the base members 4 through the intermediation of a plurality of pillars 5.

A plurality of transverse beams 2 are provided on each of the longitudinal beams 3. Each of the transverse beams 2 has a longitudinal direction “B” along a direction orthogonal to a longitudinal direction “A” of each of the longitudinal beams 3.

On the transverse beams 2, a plate-like solar panel module 1 illustrated in FIG. 6 is fixed with an adhesive, or a fixing member such as a bolt and a screw.

As illustrated in FIG. 2 in an enlarged manner, each transverse beam 2 is formed of a single-lip channel steel bar including a channel steel bar body 10 having a C-shape in overall cross-sectional view. On both sides of a back plate 12 of the transverse beam 2, a first side plate 14 including a lip 13, and a right-angled plate 15 including no lip 13 are formed, respectively. The right-angled plate 15 is formed only of a flat-plate-like flat surface portion and forms a right angle with the back plate 12.

The right-angled plate 15 extends in a right-angled direction orthogonal to a plate height direction 12 a of the back plate 12, and includes no lip 13. Accordingly, the right-angled plate 15 is formed only of a flat plate so as to prevent formation of puddles.

Note that, as illustrated also in FIG. 3, in a case where a force indicated by an arrow C is applied to the transverse beam 2 and thus a load test is performed, the entire transverse beam 2 bends to a medium extent as indicated by a dotted line and a solid line. Therefore, the transverse beam 2 has a sufficient load capacity.

In addition, the longitudinal direction “A” of the longitudinal beam 3 is oblique in FIG. 1, and hence even the same double-lip channel steel bar as that used in the conventional configuration is applicable as the longitudinal beam 3. However, the single-lip channel steel bar of FIG. 2 having the same configuration as that of the transverse beam 2 can be used as the longitudinal beam 3.

Next, in a case of another embodiment of the present invention illustrated in FIGS. 4 to 6, each longitudinal beam 3 provided on the base members 4 is disposed in a horizontal state, and the plurality of transverse beams 2 are provided on the longitudinal beam 3 so as to be orthogonal to the longitudinal beam 3. The solar panel module 1 is placed and provided on the transverse beams 2.

Therefore, all of the longitudinal beams 3, the transverse beams 2, and the solar panel module 1 provided on the base members 4 are disposed in a horizontal state, and the other structural components are the same as those of the configuration illustrated in FIGS. 1 to 3. Accordingly, herein, the same components are denoted by the same reference symbols, and description thereof is omitted.

Next, in a case of still another embodiment of the present invention illustrated in FIGS. 7 to 10, the transverse beam 2 and the longitudinal beam 3 each have a configuration different from the configurations illustrated in FIGS. 1 to 6.

That is, as illustrated in FIGS. 7 to 10, the transverse beam 2 is formed of a single-lip channel steel bar. As illustrated in FIG. 9, the back plate 12, the first side plate 14, and the lip 13 are the same as those of the configuration illustrated in FIG. 1, but the second side plate 15 is formed of a non-right-angled plate 15 a. The non-right-angled plate 15 a extends in a non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction 12 a of the back plate 12, and is formed only of a flat surface portion that is inclined downward.

Therefore, on each longitudinal beam 3 provided in a horizontal posture on the base members 4 and having a longitudinal shape, the transverse beams 2 are disposed in a horizontal posture. On the transverse beams 2, the plate-like solar panel module 1 is placed and disposed in a horizontal state.

The longitudinal beam 3 has the same structure as that of the transverse beam 2. In a case where the longitudinal beam 3 is placed on the base members 4, an inclined member 20 having a wedge shape is interposed between the non-right-angled plate 15 a and each of the base members 4, and the inclined member 20 is interposed also between the longitudinal beam 3 and the non-right-angled plate 15 a of each of the transverse beams 2. In this manner, the solar panel module 1, the transverse beams 2, and the longitudinal beams 3 can be disposed in a horizontal state on the base members 4.

The non-right-angled plate 15 a of each of the beams 2, 3 extends to be inclined downward. Accordingly, for example, as illustrated in FIG. 8, water is not collected on the non-right-angled plate 15 a and is completely drained away. As a result, durability of each of the beams 2, 3 is significantly enhanced.

Next, FIGS. 11 and 12 illustrate an assembly configuration of each of the beams 2, 3 in a case where each of the beams 2, 3 illustrated in FIGS. 7 to 10 includes the non-right-angled plate as the second side plate 15 a.

That is, as illustrated in FIG. 11, the inclined member 20 is fitted onto an anchor bolt 21 of the base member 4, and the longitudinal beam 3 is placed and fitted onto the anchor bolt 21.

Further, as illustrated in FIG. 12, the inclined member 20 is fitted onto a bolt 22 of the longitudinal beam 3 provided on the base member 4, and the transverse beam 2 is laid on the inclined member 20 and fitted onto the anchor bolt 22 through a hole 2 a of the transverse beam 2.

Therefore, according to the above-mentioned configuration, the longitudinal beam 3 and the transverse beam 2 are arranged to be orthogonal to each other and arranged to be stacked vertically.

FIGS. 13 and 14 illustrate the configuration after completion of assembly of the beams 2, 3 illustrated in FIG. 12. FIG. 13 illustrates a lateral view of the transverse beam 2 that is fastened with a nut 25. FIG. 14 illustrates a longitudinal view of the transverse beam 2.

Note that, an inclined washer 30 and a nut 31 are used to fix the longitudinal beam 3 as illustrated in FIG. 13, and the inclined washer 30 is used to fix the transverse beam 2 as illustrated in FIG. 14.

Next, configuration diagrams of FIGS. 15 to 29 illustrate single-lip channel steel bars according to still other embodiments of the present invention.

Note that, the same or corresponding components as those used in the conventional example and the configurations illustrated in FIGS. 1 to 14 are denoted by the same reference symbols, and description thereof is omitted. Configurations illustrated in FIGS. 15 to 29 are different from the configurations illustrated in FIGS. 1 to 14 in that a protruding length of the second side plate 15 and a protruding length of the second side plate 15 a are smaller than the protruding length used in the configuration illustrated in FIG. 2.

Reference numeral 4 of FIG. 15 denotes the base members. The longitudinal beams 3 are supported in an inclined state on the base members 4 through the intermediation of the plurality of pillars 5.

The plurality of transverse beams 2 are provided on each of the longitudinal beams 3. Each of the transverse beams 2 has the longitudinal direction “B” along the direction orthogonal to the longitudinal direction “A” of each of the longitudinal beams 3.

On the transverse beams 2, the plate-like solar panel module 1 illustrated in FIG. 6 is fixed with an adhesive, or a fixing member such as a bolt and a screw.

As illustrated in FIG. 16 in an enlarged manner, each transverse beam 2 is formed of a single-lip channel steel bar including the channel steel bar body 10 having an L-shape in overall cross-sectional view. On one side portion of the back plate 12 of the transverse beam 2, the first side plate 14 including the lip 13 is formed. On the other side portion thereof, the second side plate 15 is formed. The second side plate 15 is formed of a right-angled plate that is formed only of a flat-plate-like flat surface portion. Note that, the lip 13 and the second side plate 15 have the same protruding length, and hence the transverse beam 2 apparently has a double-lip shape . However, the second side plate 15 may have a slightly larger length than that of the lip 13.

The second side plate 15 as the right-angled plate extends in the right-angled direction orthogonal to the plate height direction 12 a of the back plate 12, and includes no lip 13. Accordingly, the second side plate 15 is formed only of a flat plate so as to prevent formation of puddles.

Note that, as illustrated also in FIG. 18, in a case where the force indicated by the arrow C is applied to the transverse beam 2 and thus the load test is performed, the entire transverse beam 2 bends to a medium extent as indicated by a dotted line and a solid line. Therefore, the transverse beam 2 has a sufficient load capacity.

In addition, the longitudinal direction “A” of the longitudinal beam 3 is oblique in FIG. 15, and hence even the same double-lip channel steel bar as that used in the conventional configuration is applicable as the longitudinal beam 3. However, the single-lip channel steel bar of FIG, 16 having the same configuration as that of the transverse beam 2 can be used as the longitudinal beam 3.

Note that, a side plate width W₁ of the side plate 14 extending in a direction orthogonal to the longitudinal direction “A” is smaller than a back plate width W₂ of the back plate 12 extending in another direction orthogonal to the longitudinal direction “A”. In a case of another embodiment illustrated in FIG. 17 corresponding to FIG. 16, the second side plate 15 is formed of a lip, and the plate width W₁ of the side plate 14 and the plate width W₂ of the back plate 12, which respectively extend in the directions orthogonal to the longitudinal direction “A”, are equal to each other. The lip 13, the second side plate 15, the first side plate 14, and the back plate 12 form a single-lip angle steel bar 40 as a single-lip channel steel bar, and provide the same actions on drainage and the like as those of the above-mentioned embodiment illustrated in FIG. 16.

Further, a first protruding length WA of the second side plate 15 protruding from the back plate 12, or a first protruding length WA of the second side plate 15 a protruding from the back plate 12 is equal to a second protruding length WB of the lip 13 protruding from the first side plate 14.

Next, in a case of still another embodiment of the present invention illustrated in FIGS. 19 and 20, each longitudinal beam 3 provided on the base members 4 is disposed in a horizontal state, and the plurality of transverse beams 2 are provided on the longitudinal beam 3 so as to be orthogonal to the longitudinal beam 3. The solar panel module 1 illustrated in FIG. 6 is placed and provided on the transverse beams 2.

Therefore, all of the longitudinal beams 3, the transverse beams 2, and the solar panel module 1 provided on the base members 4 are disposed in a horizontal state, and the other structural components are the same as those of the configuration illustrated in FIGS. 15 to 18. Accordingly, herein, the same components are denoted by the same reference symbols, and description thereof is omitted.

Next, in a case of still another embodiment of the present invention illustrated in FIGS. 23 to 25, the transverse beam 2 and the longitudinal beam 3 each have a configuration different from the configurations illustrated in FIGS. 15 to 20.

That is, as illustrated in FIGS. 23 to 25, the transverse beam 2 is formed of a single-lip channel steel bar corresponding to the single-lip channel steel bars 2, 3 in the other embodiments illustrated in FIGS. 16 and 17. As illustrated in FIGS. 21 and 22, the back plate 12, the side plate 14, and the lip 13 are the same as those of the configurations illustrated in FIGS. 16 and 17, but the second side plate 15 is formed of the non-right-angled plate 15 a. The non-right-angled plate 15 a extends in the non-right-angled direction inclined at 90 degrees or more with respect to the plate height direction 12 a of the back plate 12, and is formed only of the flat surface portion that is inclined downward.

Therefore, on each longitudinal beam 3 provided in a horizontal posture on the base members 4 and having a longitudinal shape, the transverse beams 2 are disposed in a horizontal posture. On the transverse beams 2, the plate-like solar panel module 1 is placed and disposed in a horizontal state.

The longitudinal beam 3 has the same structure as that of the transverse beam 2. In a case where the longitudinal beam 3 is placed on the base members 4, the inclined member 20 having a wedge shape is interposed between the non-right-angled plate 15 a as the second side plate 15 and each of the base members 4, and the inclined member 20 is interposed also between the longitudinal beam 3 and the non-right-angled plate 15 a of each of the transverse beams 2. In this mariner, the solar panel module 1, the transverse beams 2, and the longitudinal beams 3 can be disposed in a horizontal state on the base members 4.

The non-right-angled plate 15 a of each of the beams 2, 3 extends to be inclined downward. Accordingly, for example, unlike the conventional configuration illustrated in FIG. 31, water is not collected on the non-right-angled plate 15 a and is completely drained away. As a result, durability of each of the beams 2, 3 is significantly enhanced.

Next, FIGS. 26 and 27 illustrate an assembly configuration of each of the beams 2, 3 in a case where each of the beams 2, 3 illustrated in FIGS. 10 to 12 includes the non-right-angled plate as the second side plate 15 a.

That is, as illustrated in FIG. 26, the inclined member 20 is fitted onto the anchor bolt 21 of the base member 4, and the longitudinal beam 3 is placed and fitted onto the anchor bolt 21.

Further, as illustrated in FIG. 27, the inclined member 20 is fitted onto the bolt 22 of the longitudinal beam 3 provided on the base member 4, and the transverse beam 2 is laid on the inclined member 20 and fitted onto the anchor bolt 22 through the hole 2 a of the transverse beam 2.

Therefore, according to the above-mentioned configuration, the longitudinal beam 3 and the transverse beam 2 are arranged to be orthogonal to each other and arranged to be stacked vertically.

FIGS. 28 and 29 illustrate the configuration after completion of assembly of the beams 2, 3 illustrated in FIG. 27. FIG. 28 illustrates a lateral view of the transverse beam 2 that is fastened with the nut 25. FIG. 29 illustrates a longitudinal view of the transverse beam 2.

Note that, the inclined washer 30 and the nut 31 are used to fix the longitudinal beam 3 as illustrated in FIG. 28, and the inclined washer 30 is used to fix the transverse beam 2 as illustrated in FIG. 29.
